EXtra-solar planets and stellar astrophysics:
towards the detection of Other Earths

The detection of about 4000 extrasolar planets orbiting other solar-like stars opened the window to a new field of astrophysics. Many projects to search for Earth-like planets are now currently under way, using a huge battery of telescopes and instruments. New instrumentation is also being developed towards this goal for use in both ground- and space-based facilities.

Since planets come as an output of the star formation process, the study of the stars hosting planets is of great importance. The stellar-planet connection is strengthened by the fact that the most successful planet discovery techniques (radial velocity and transit photometry) only observe the star and the influence that the planet has on its measurable properties.

In this context, the scientific activities of the EXOEarths team focus in two main lines that complement each other, providing a unique, comprehensive approach to the field of Planetary Systems:

  1. The detection and full characterization of exoplanets using state-of-the-art instrumentation;
  2. The characterization of the host star of the system, with the goal of understanding the link between the star- and planet-formation processes.

These strategic lines are consolidated by our key participation in several key projects for ground and space based instruments such as ESPRESSO and NIRPS (ESO), and CHEOPS and PLATO (ESA).
